The invention discloses a pressure cover, an expansion kettle assembly and a vehicle, the pressure cover comprises a cover body arranged outside a filling port of the expansion kettle assembly in a sleeving mode, at least one opening is formed in the cover body, an air bag is connected with the opening in a sealed mode, and the air bag expands or shrinks according to pressure changes in the expansion kettle assembly. The expansion kettle assembly comprises a shell, a filling port is formed in the top end of the shell, and the filling port is sealed through the pressure cover. A containing cavity communicated with the filling port is formed in the shell, a plurality of first connectors communicated with the containing cavity are formed in the upper portion of the shell, and the first connectors are communicated with the liquid outlet end of an engine cooling assembly. A second connector communicating with the lowest point of the containing cavity is formed in the lower portion of the shell and communicates with the liquid inlet end of the engine cooling assembly. It can be guaranteed that the gas pressure in the expansion kettle is basically kept consistent with the environment pressure.
